Specification-of Letters Patent. Patented 4,1919.

to providenovel means for imparting rightline movement to a slide valve, and another object of the invention is to provide novel means whereby a-signal may be givenata certain point in the travel of the valve, the

structure-being of peculiar utility when employed in connection with a baling press in packing ortramping cotton.

It is within the provinceof the disclosure to improve generally and to enhance the utility of devices of that typeto which the present invention appertains.

With the above and other objects in view, which. will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details'of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departingfrom the spirit of the invention.

In the accompanying drawings :v

Figure 1 shows a longitudinal section, a device constructed in accordance with the present invention, parts appearing in elevation; Fig. 2 is a cross section on the-line 2-2 of Fig. 1; and Fig. 3 is a cross section on the line 33 of Fig. 1.

In carrying out the present invention there is provided a supporting structure which may include a base plate 1 having lugs 2 carrying a cylindrical casing 3, the lugs being attached to the casing shown at 1. The casing 3 includes anend wall 5 and an end wall 6, the latter end wall comprising a bearing 7 in which a shaft 8 is mounted for rotation, the shaft being jour-naled, also, in a standard 9 carried by the base plate 1. Outside of the casing 3, the shaft 8 carries pulleys 10, one of which is fixed, and the other of which is loose. A bracket 11 is mounted on the top ofthe casing 3 at one end thereof, a lever 12 being mounted to swing on the bracket. A belt shifter 14 is connected with the lever 12 and coperates with the pulleys 10. The lever 12 may be operated by hand, or it may be operated automatically, these details constituting no part-of the present invention.

A pinion 15 is fixed to the shaft 8 and meshes into agear wheel 16 .journaled on a stub shaft 17 carried 'by the end wall 6 of the casing 3. 'Thegear wheel 16 meshes intoan internalgear 18 constituting a part of awheel 19, journaled on the shaft 8. The wheel 19 has an internal gear 20 meshing into apinion 21 secured to one end of a shaft 22 :journaled in bearings 23 which are mounted on and within the easing 3. The shaft 22 carries a pinion 24E meshing into an internal gear 25 constituting a part of a wheel 26 journaled on a valve stem 27, the valve stem being mounted to move endwise in the hub 28. of the wheel- 26 and in the end wall 5of the casing 3. The hub 28 of the wheel 26 is provided with a circumscribing seat 29 which is inclined with respect to the axis of the hub 28. The numeral 30marks a U-shaped frame including ahead 31 secured at 32 to the inner end of the valve stem 27 the frame being mounted to slide endwise in lugs 33 constituting a part of aguide 34: attached to the casing 3 and located within the casing. The frame 30 includes a depending finger 35 slidably receivedin the circumscribing seat'29 of the hub 28 of the wheel 26. A steam chest 36 is arranged exteriorly of the casing3 and may be connectedby means of a support 37 with the end wall 5 of the casing. An inlet pipe38 communicates with the steam chest 36, an outlet'pipe 39 leads from the steam chest, and from the steam chest eX- tends an outlet pipe 40. The outlet pipe 39 leads to the lower end of the steam cylinder of the press .(not shown) and the outlet pipe 40 leads to the upper end of the cylinder. An exhaust pipe 41 communicates with the steam pipe chest 36. A slide valve 42 is mounted to reciprocate in the steam chest 36 and controls the pipes 39, 41 and 40. The valve stem 27 enters the chest 36 and the slide valve 42 is connected to the valve stem.

A pipe 43 leads from the steam supply pipe 38 and is connected at 44 with the casin 3. The pipe &3 carries an audible signa 15, which may be a=whistle, the numeral 16 denoting an arm which may be operated to admitsteam to the whistle 45 from the .pi-pe 13. The whistle arm 46 is controlled by a lever 4:7 fulcrumed between its ends,

as shown at 48, on the casing 3, the lower end of the lever entering the casing and the pinion 15 on the shaft will be rotated,

rotation being imparted to the gear wheel 16 on the shaft 17,'the gear wheel cocperating with the internalgear 18 to rotate the wheel 19, and the wheel 19 rotating the shaft 22 by way'of theinternal gear 20 and the pinion 21. WVhen the shaft 22 is rotated, the pinion 24 cooperating with the internal gear 25, will rotate the Wheel 26. When the Wheel 26 is rotated, the circumscribing seat 29 in the hub 28'of the wheel, coacting with the finger 35 on the U-shaped frame 30, will impart right-line sliding movement to the frame, the frame reciprocating in the guide structure 3438. Since the head 31 of the frame 30 is connected at 32 to-the valve stem 27, thetvalve stem will reciprocate in the hub 28 of the wheel 26 and in the end wall 5 of the casing 3, the slide valve 42 being operated in a manner which will be entirely clear when the drawings are examined.

I/Vhen the valve stem 27 moves to the left (Fig. 1) the lower end of the lever 48 is engaged by the valve stem, and the lever is tilted, the arm 46 being operated, when the whistle 45 being sounded, pressure being supplied to the whistle, from the pipe 38, by way of the pipe 43. The purpose of the whistle 45 is to give a signal when the presser foot of the baler descends, so that, if the operators are busy about the baler of which the presser foot constitutes a part, they will be advised that the presser foot is about to descend, and may assume a position of safety. 7

The casing 3 serves to house and protect the working parts of the device, so that the same will not be likely to be clogged by lint or other foreign material.

' Having thus described the invention, what is claimed is 1. In a device of the class described, a stem; a support wherein the stem is mounted for right-line sliding movement; a rotary member journaled on the stem; means for driving the rotary member; means for imparting right-line sliding movement to the stem from the rotary member; a signal; and

Copies of this patent may be obtained for a signal-operating means disposed in the path of the stem.

2. In a device of the class described, a stem, a support wherein the stem is mounted for right-line sliding movement; a rotary 3. In a device of the class described, a

support; a stem mounted for right-line sliding movement in the support; a first shaft journaled on the support; gear wheels journaled on the stem and on the shaft; a gear train connecting the gear wheel of the shaft with the shaft; a second shaft journaled on the support; pini'ons carried by the second shaft and connected with the gear wheels; means for driving the first shaft; means for imparting right-line sliding movement to the stem from the gear wheel which is journaled on the stem; and a signal operated by the stem.

4. .In a device of the class described; a casing; a valve operating in the casing; means for actuating the valve; an audible signal; and mechanism located in the path of the actuating means for operating the signal. r

5. In a device of the class described; a casing; a valve mounted to move in the casing; means for actuating the valve; a supply pipe leading to the casing; an outlet pipe leading from the casing; an audible signal sounded by fluid pressure; means for conveying fluid pressure fro-m the supply pipe to the signal; and a controlling device for the signal, the controlling device lying in the path of the actuating means for the valve.

6. In a device of the class described, a casing; avalve working in the casing; means for actuating the valve; a'signal responsive to fluid pressure; means for operating the signal, said means extending into the path of the actuating means of the valves; and a single conduit having branches leading, re

spectively, to the valve casing and to the signal.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
